nanoporous ag-cnts foamed electrode for lithium intercalation
Authors
abstract
intercalation of lithium into ag-cnts sample is reported here. we have used a nano-porous silver foam as a frame for deposition of the cnts inside the pores by electrophoresis deposition (epd) technique. by using chronopotentiometry method, we have noticed that the li storage capacity of the prepared ag-cnts electrode was improved noticeably in comparison with literature. in addition, a very good functional stability for the prepared electrode has been tested during subsequent cycles of charge / discharge (c&d) procedures. by scanning the cycle's regulated current from 0.2 up to 1.0 ma , it was shown that in the range of 0.4–0.6 ma reversibility of the c&d capacity became optimum and the voltage profiles were converged, as well.

full textLi(V0.5Ti0.5)S2 as a 1 V lithium intercalation electrode
Graphite, the dominant anode in rechargeable lithium batteries, operates at ∼ 0.1 V versus Li(+)/Li and can result in lithium plating on the graphite surface, raising safety concerns. Titanates, for example, Li4Ti5O12, intercalate lithium at ∼ 1.6 V versus Li(+)/Li, avoiding problematic lithium plating at the expense of reduced cell voltage. There is interest in 1 V anodes, as this voltage is s...
full textFlame treatment of graphene oxides: cost-effective production of nanoporous graphene electrode for Lithium-ion batteries
A facile production of highly porous graphene foam by using flame treatment of graphene oxide (GO) is proposed. Highly porous architectures with randomly distributed micro-crack and micro-slit were produced due to the high temperature induced ruinous reduction and rapid expansion of GO. Synchronously, abundant oxygen-containing groups (OCGs) on GO sheets could be effectively removed after flame...

The MWCNTs-COOH Paste Electrode (MCPE) was successfully used to study the electrochemical behavior of temozolomide in 0.2 M H2SO4 solution, phosphate buffer solution (0.1M PBS, pH 7.4) and 0.1M NaOH solution by Cyclic Voltammetry (CV) technique. The results exhibit that MCPE can remarkably enhance sensing and electrocatalytic activity towards the oxidation and reductio...

Nanoporous metals similar to paper in form are developed using Japanese washi paper as a template to create hierarchical porous electrodes. This method is used to create a trimodal -nanoporous Au electrode, as a well as a hierarchical NiMn electrode that achieves high electrochemical capacitance and a rapid rate of oxygen evolution.
full textElectrode Materials for Lithium Ion Batteries: A Review
Electrochemical energy storage systems are categorized into different types, according to their mechanisms, including capacitors, supercapacitors, batteries and fuel cells. All battery systems include some main components: anode, cathode, an aqueous/non-aqueous electrolyte and a membrane that separates anode and cathode while being permeable to ions. Being one of the key parts of any new electr...
